My timid sister, a maiden, solicits me to initiate intercourse with her and I climax on her derriere, in a domestic setting

In the sanctity of our home, my timid sister, a pure and innocent maiden, approached me with a request to guide her through the uncharted territory of carnal pleasure. Her youthful allure and tantalizing curves were impossible to resist. I obliged, eager to satiate her insatiable curiosity. As I undressed her, her luscious Latina body became bare, revealing her ample bosom and voluptuous derriere. I couldn't help but be captivated by her irresistible charm. I began to explore her petite, rosie treasure, teasing her with my fingers until she was moist and ready for my throbbing member. I plunged into her, eliciting sweet moans of pleasure. Despite her inexperience, she matched my rhythm, her body writhing in ecstasy. As I reached my climax, I lavished her derriere with my warm, sticky essence, marking her as mine. This intimate encounter left us both breathless, our bodies entwined in the afterglow of our shared passion.
